Computer won't start.

It's not that the battery doesn't work, because the small lightning symbol comes on when i plug the adapter in. when i press the power button, the caps lock and scroll buttons light up as they're supposed to every time you start the computer...but then they keep blinking, and so does the light from the dvd-rom, and the OS itself never starts up. the lights just blink forever until i shut the computer off. nothing loads. please help me out someone because if i lose this computer i lose everything i've ever done for the past 2 years. thanks

nothing comes up on the screen at all. no software of any kind boots upon starting the computer. no bios, no windows xp loading screen, no light, nothing. all that turns on are the power light and the two small orange lights beside the scroll and caps lock buttons, and they flicker on and off simultaneously. nothing more.nothing comes up on the screen at all. no software of any kind boots upon starting the computer. no bios, no windows xp loading screen, no light, nothing. all that turns on are the power light and the two small orange lights beside the scroll and caps lock buttons, and they flicker on and off simultaneously. nothing more.

* Insert the XP CD and boot to it* When you see " To setup Windows XP now, press ENTER", go ahead and press ENTER* You will now see an option to repair Windows by pressing "R". Do not select this option - it will only take you to the Recovery Console which is not what we want to do. Instead, choose to continue the installation* When you see the license agreement, press F8 to agree* On the next screen make sure your current XP installation is selected and then press "R" to repair XP* At this point XP will begin to install on top of itself, replacing damaged, missing or altered system files. Follow the instructions on the remaining screens to complete the Repair Install. It will look very much like a normal (new) OS installation.

If all goes well your repaired XP installation will remain intact, keeping your personalized settings and installed programs as they originally were.I think you should do a repair install.

If you do the repair install like I suggested, this will fix your problem. Don't worry, when you do this you won't lose any of your files, settings, or installed programs. It only replaces the windows OS files.If you do the repair install like I suggested, this will fix your problem.

First, check to make sure you're not in the macro mode. There's a slide switch on the end of the camera, near the SD card slot. Slide the switch away from the flower toward the mountain to take it out of macro mode. The flash won't fire in macro mode.

Then, if the flash still doesn't fire, take a look at the flash mode. Press the up-arrow button to bring up the flash menu. If it's currently set in the lightning-bolt-in-a-circle-with-a-slash-through-it symbol, you've got the flash turned off. Set it to the lightning-bolt-and-"A" for automatic flash or the lightning-bolt for forced flash.

Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.

If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the fluorescent pen computer with the adapter connected to recharge the battery.

Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the PowerBook G4 Battery 15" power adapter LEDs should light up green or amber.

Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.

Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter,learn which adapter is appropriate for your computer.

Press the control key, the command key, and the sony vgp-bps13a/b battery power button simultaneously and hold for three seconds to try to restart the computer.

Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.

Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the sony vgp-bps13 battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.

If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.

If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider.

do the hard reset again .. hold the power button down while operating the reset in the back .. keep the power button down for a few seconds .. that should bring up a display "delete all" .. you can choose to do so .. that will be a hard reset .. now if the battery is dead and the charger is not working then nothing will work for you .. you might have a bad charger .. often the end that plugs into the unit develops a broken wire inside the cable ..
the m515 wont charge from the sync cable (shame) it needs the external power adapter .. make sure the connections on the charger and palm are clean .. the power adapter is 5 volts and i think about 1 amp .. )(center pos) if you want to try another adapter .. the tip is rather standard ... also you can get a universal power adapter from radio shack that will work on just about anything .. you just plug in a suitable tip .. the tip for your palm is an "A19" .. the power adapter is "IGO" wall adapter 23-1401 model PSM08VADJ ... that seems to work nicely and it plugs directly in to the palm .. so you can work with it plugged in .. when the charger is working there should be a lightning bolt thru the battery symbol .. it sounds like you already know that .. if the battery has gone open then it may not indicate a charge .. but the unit should still work while on the charger if that is actually working ....

When the computer is off, unplug the power cord from the laptop and then plug it back in. See if the charge light (lightning bolt symbol next to the led) comes on or turns green/blue. If it doesn't your power supply may not be working, even if the light on the supply is on. Second is the battery may be damaged. Remove the battery and see if you can power on at all.
If it boots with only the cord, the battery is bad/shorted forcing shutdown.

Hi,Remove the adapter and the battery from the laptop.
Press the power button and hold it down for 20 seconds(without the
battery or adapter plugged in to it). This process is called POWER
DRAIN.
Now connect only the adapter and try to turn it on.
If it starts up, there is no problem with the adapter or the laptop.
If it doesn't, it can be either the adapter or the laptop.
You will have to check it with a different adapter to confirm which one is faulty.

The second case is that the computer powers on only with the adapter.
Then you can put the battery back in and try powering it up.
If it doesn't work, try connecting the adapter too.
If still it doesn't work, its a faulty battery.

Sometimes after doing a power drain, the computer will work fine.
If you have any more issues, feel free to contact me.
